I haven't read the spoilers, no, and I'm not going to. First of all, the vast majority of the anger aimed at them is completely manufactured and people trolling. And all this "I'm not buying the game now after what I've read" bollox is coming from people who, 90% of them, weren't going to buy the game anyway. And if you're purely basing your opinion on an unreleased game from leaks that are taken out of context then more fool you.
Also, Naughty Dog has been taking shit for years since the release of the first Last of Us. And we all know why. This is just another opportunity for those same people to jump in for a second time. So people posting spoilers deliberately in comments on videos and social media posts, just to be dicks, aren't justified in their actions. They're just being dicks.
